About GHRI Ratings

X

Good Housekeeping Research Institute (GHRI) ratings are based on laboratory tests conducted by our scientists at the U.S.'s foremost consumer products evaluation laboratory, and incorporate consumer feedback. GHRI is situated on the 29th floor of the Hearst Tower in New York City and is staffed by chemists, engineers, nutritionists, textile specialists, culinary experts, and other scientists.

Using state-of-the-art equipment, GHRI experts test consumer products — from microwaves to mascaras — for their performance, safety, and, with the help of volunteer testers, ease of use.

Established in 1900, before there was a Federal Drug Administration or a Federal Trade Commission, GHRI has always been the most trusted source consumers can rely on to choose products that are safe and effective.

Pros

Durable

Repels water well

Light weight and folds up for easy portability

Adjustable

Cons

Aesthetic is definitely not for everyone

Consumer testers noted that Koss' Porta Pro pair was just mediocre in terms of comfort

Consumer testers noted that Koss' Porta Pro pair was just mediocre in terms of comfort, and sound quality also earned middling scores in GHRI tests. But the headphones were the most portable of the bunch we tested, thanks to their fold-up design. Plus they're durable: In our tests, the Porta Pro withstood several drops and did a great job resisting water. koss.com.
